GeoTools Does not support DataSource from an application server

I have set up a connection pool / data source in WebLogic to PostgreSQL.
How do I use that data source in Geotools ?
All the APIs I can find need a javax.sql.ConnectionPoolDataSource or
needs you to set user/password/connection info ... in a Map.
That is already set up inside of WebLogic and I don't have access to that info.
Is there a way to give geotools the connection to use or tell it to use a DataSource ?
I don't want to have to have a hard coded properties file with the login info. (passwords need to be changed
and I would rather have them use WebLogic's console than change a properties file by hand.)
